“…In this configuration, the detection scheme by the ZnO nanorods is based on two factors. First is the alteration of surrounding refractive index and the second is the change in electrical conductivity of the ZnO nanorods due to adsorption process upon exposure to the vapor concentrations [43], [44].…”

“…During the vapor sensing experiment, formaldehyde vapor varies the refractive index of the nanorods surroundings. The adsorption of the vapor molecules by nanorods changed the electrical conductivity of the material [43], [44]. Therefore, the complex refractive index of the ZnO nanorods was altered due to the changing of electrical conductivity thus affects the optical scattering patterns on ZnO nanorods.…”

A glass substrate coated with ZnO nanorods via a hydrothermal method for formaldehyde vapor sensing is reported. The proposed sensor device was characterized against formaldehyde vapor concentrations varying from 1% to 5% with a reference point as 0% (pure water) at room temperature. A significant sensing response was observed where the output voltage reduced by 0.0856 V via scattering effect by ZnO nanorods upon exposure to the maximum tested concentration (5%). The sensitivity and linearity of the sensing response were recorded to be approximate values of −0.0168 V/% and 98.06% correspondingly. The sensor device was found to have good measurement stability in measuring as low as 1% of concentration for a prolonged time of 600 s. This proposed sensor has potential applications in monitoring air pollution caused not only by formaldehyde vapor but also by other harmful and toxic vapors or gases.
